2. Principle of Display Control

FIG. 3 is a schematic view showing a detailed display control of theinformation processing system in accordance with this embodiment. InFIG. 3, the like components disclosed in FIG. 1 are suffixed by the samereference numerals.

Hereinafter, referring to FIG. 3, a principle of display control will beexplained. Let's suppose that three different data, e.g. a charactercode "ABC", a shaded rectangle pattern, and a circle surrounding thecharacter code "123", are displayed on the LCD 2.

In this embodiment, the VRAM 4 memorizes these data by separating theminto a plurality of text plane screens #1˜N and one image plane screen#1.

Upon display requirement, the CPU 1, first of all, reads out charactercodes "ABC", "123", and graphic data "rectangle" and "circle" from theROM 9 and transmits them to the LCD controller 3. Then the LCDcontroller 3 obtains dot patterns corresponding to the receivedcharacter codes "ABC", "123" from the first CG 5 and temporarilymemorizes them in the text plane screen #1 of the VRAM 4. Furthermore,the LCD controller 3 temporarily memorizes the received graphic data"rectangle", "circle" in the image plane screen #1 of the VRAM 4.Thereafter, the LCD controller 3 sums or composes the text plane screen#1 and the image plane screen #1 and displays a composite image on theLCD 2.

Separating display data into a plurality of screens in this manner isadvantageous in the realization of speedy change in display. Forexample, in order to respond to the request of changing "ABC" to "XYZ",this embodiment prepares two text plane screens #1 and #2. In this casethe text plane screen #1 memorizes "ABC" and "123", while the text planescreen #2 memorizes "XYZ" and "123". This arrangement not only realizesthe speedy display change by simply exchanging the text plane screen #1for the text plane screen #2 but requires no necessity of rewritingcontent of the VRAM 4. Thus, no flickering will occur when the displayscreen is changed over.

Although this embodiment provides only one image plane screen, it isneedless to say that it is possible to prepare a plurality of imageplane screens in the VRAM 4.

Next explained in detail will be the way of displaying the appearance orphysical condition change of the apparatus, which is to be displayed onthe LCD 2. In this embodiment, the graphic data to be displayed on theLCD 2 is separated into two, right and left, regions having the samearea, each of which is memorized in the VRAM 4. In order to effectivelyutilize the memory capacity of the ROM 9, it should be noted that theposition of a split line in the separation above described is determinedby taking account of frequency in appearance change of the apparatus.

In more detail, it would be preferable that one of two, right and left,regions chiefly includes the part whose appearance is frequentlychanged. The other region would contains a common part whose appearanceseldom change. In this embodiment, the right region memorizes the mainbody of the apparatus as shown in FIGS. 4(c)˜4(f). Therefore, the centerof the apparatus main body is offset toward right with respect to thesplit line between the right and left regions. On the other hand, theleft region only memorizes a left edge of the apparatus as shown inFIGS. 4(a) and 4(b). The VRAM 4 can selectively combine right and leftregions among these appearances shown FIGS. 4(a)˜4(f). In other words,the VRAM 4 can give variation in appearance of the apparatus as many asthe number of possible combination given by FIGS. 4(a)˜4(f).

Furthermore, the memorization or administration of graphic data in thismanner can realize the speedy change in display because the graphic datato be displayed are separated into two, right and left, regions. Forexample, if required to change only left edge of the apparatus, displaychange can be quickly performed by simply exchanging FIG. 4(a) for FIG.4(b).

Next, the way of completing one appearance view, performed in the LCDcontroller 3, by summing or composing the divided graphic data will beexplained in detail.

FIG. 5 is a schematic view showing a memory map of the VRAM 4, whichillustrates the relationship between an entire memory space and thememory space provided for the LCD 2. This memory space for the LCD 2specifically illustrates the graphic data corresponding to theappearance of the apparatus.

In FIG. 5, a reference numeral 31 represents the entire memory space ofthe VRAM 4, and a reference numeral 32 represents the memory spaceprepared for the LCD 2. A reference numeral 33 represents the graphicdata exclusively showing the left edge of the apparatus, and a referencenumeral 34 represents the graphic data exclusively showing the main bodyof the apparatus. That is, the memory space that the LCD 2 displaysunder the control of the LCD controller 3 is identical with the space ofthese graphic data 33, 34.

Referring now to FIG. 5, how the LCD controller 3 displays theappearance of the apparatus on the LCD 2 will be explained. The VRAM 4used in this embodiment has 40 bytes per lateral line as shown in FIG.5. Meanwhile, the right and left graphic data 33, 34 have respectively 8bytes per lateral line.

In order to display the left pattern of the appearance prior to theright pattern, the CPU 1 sends the LCD controller 3 the commandspecifying graphic data to be displayed and its address on the VRAM 4.The LCD controller 3 obtains the dot pattern corresponding to thespecified graphic data from the ROM 9 and transfers this dot pattern tothe specified address on the VRAM 4. In this case the VRAM 4 has 40bytes per lateral line as described above, while the right and leftgraphic data, showing appearance of the apparatus, are stored in the ROM9 to have 8 bytes per lateral line respectively.

With this arrangement, every time the LCD controller 3 transfers an 8bytes graphic data corresponding to the left appearance of theapparatus, the LCD controller 3 renews a start address designating 8bytes for the next graphic data by simply adding 40 bytes. Accordinglythe start address always coincides with previous one in the lateraldirection; therefore the transfer of divided graphic data to the VRAM 4can be simplified.

Next, the transfer of right pattern of the appearance is carried out inthe same manner. After the graphic data to be display and its addressare specified, the specified graphic data can be simply transferred tothe VRAM 4 through the similar procedure.

If this embodiment is modified to adopt a plurality of image planescreens, these right and left graphic data can be memorized intodifferent image plane screens. This modification will allow the speedychange in display because the LCD controller 3 needs not rewrite thecontent of the VRAM 4 every time the display content is changed. Allthing to do for the LCD controller 3 is to select either one of imageplane screens to be displayed. Furthermore, it is needless to say thatthe graphic data can be divided into three or more. In this case, itshould be also noted that the split lines of the graphic data aredetermined by taking account of frequency of physical change inappearance of the apparatus in order to save the memory in the ROM 9.

3. Overall Display Operation

An operation of the information processing system of this embodimentwill be explained in more detail, with reference to the flowcharts ofFIGS. 6 to 8. FIG. 6 is a flowchart showing action from turning-on of anelectric power to standing-by for various operations. FIGS. 7 and 8 areflowcharts showing action in the case a memory card is connected to theapparatus.

After the electric power is turned on, an input/output circuit isinitialized in a step ST1. Next, the CPU 1 checks a memory cardinterface (abbreviated by IF hereinafter) to judge whether or nor thememory card is inserted, and sets a confirmation flag indicating thepresence of the memory card in a step ST2. This check action will bedescribed later in more detail together with insertion/extractioncontrol of the memory card. However, from the explanation describedsimply here it will be understood that the CPU 1 operates differentlydepending on the presence of memory card.

It is checked whether or not the memory card is inserted in a step ST3.If the memory card is inserted, the CPU 1 proceeds to a card processingroutine later described. If not, the CPU 1 executes the followingprocedure.

The CPU 1 initializes the content of VRAM 4 used for display on the LCD2 in a step ST4. FIGS. 10 through 12 show initial screens displayed onthe LCD 2 respectively, in which FIG. 10 shows an initial screendisplayed on the LCD 2 when the memory card is not inserted into theapparatus while FIGS. 11 and 12 show initial screens displayed when thememory card is inserted.

To display the initial screen of FIG. 10, the LCD controller 3 transfersthe left graphic data of FIG. 4(a) from the RPM 9 and displays it on thetext plane screen #1 of the VRAM 4 as illustrated in FIG. 3 in a stepST5. The LCD controller 3 further transfers the right graphic data ofFIG. 4(c) from the RPM 9 and displays it on the text plane screen #1 ofthe VRAM 4 in a step ST6 and, then, sums or composes these FIGS. 4(a)and 4(c) to display a composite image on the LCD 2.

In this case, it will be preferable to prepare a plurality of imageplane screens to memorize the graphic data of FIGS. 4(a) and 4(c) intodifferent screens. It is needless to say that there is no need torewrite the content of the VRAM 4 in exchanging FIG. 4(a) for FIG. 4(b).

Next in a step ST7, the CPU 1 transfers function frames from the ROM 9and composes them onto the image plane screen #1 in the VRAM 4 throughthe LCD controller 3. As shown in FIG. 10, the function frame isdisplayed by use of both a solid line and a dotted line. This will beeffective to realize 3-dimensional display of function frames withoutspecially using lines or rows exclusively for the display of functionframes.

That is to say, in the conventional display system using a 2-dimensionalscreen, the way of realizing 3-dimensional display used to be asfollows. Like a scenography, a near part is depicted by a thick line anda faraway part by a thin line. Expression of a thick line usuallyrequires a bunch of dot rows disposed adjacent with each other. On theother hand, the way of expressing the function frame by a solid line anda dotted line in accordance with this embodiment can realize an adequate3-dimensional display without requiring additional dot lows.

Furthermore, the display of a plurality of function frames, displayedclose with each other as shown in FIG. 11, will be seen as if a dottedline of one function frame indicated a height of a solid line of nextfunction frame.

Subsequently in a step ST8, the CPU 1 composes and displays functioncharacters to be displayed in the function frame on the text planescreen #1 in the VRAM 4 through the LCD controller 3 and the 1st CG 5.

Thereafter the CPU 1 proceeds to a step ST 9 and checks a condition flag(not shown) to judge whether or not the condition of the apparatus isvariously changed. Various changes means, for example, hook on, monitoron, manuscript set, call reception, and external phone usage.Hereinafter, a first mode is referred to as hook off and monitor oncondition. Similarly, a second mode as manuscript set condition, a thirdmode as call reception condition, and a fourth mode as external phoneusage condition.

The information processing system of this embodiment changes, at equalintervals, the display position of the apparatus appearance pattern asif it circulated, e.g. in a counterclockwise direction, on the LCD 2 asshown in FIG. 12.

Before going on to the explanation of each mode, the display of the LCD2 will be more explained about the case where the condition of theapparatus is not changed. After detecting no physical condition changeof the apparatus in steps ST9 and ST10, the CPU 1 continues monitoringcondition change of the apparatus and increments a timer every constanttime in a step ST11.

Hereinafter, this timer increment process will be explained in detail.If the CPU 1 judges in a step ST11 that a predetermined time haselapsed, the CPU 1 calculates the next display position of the apparatusappearance pattern on the basis of the present position displayed on theLCD 2, and memorizes it in the RAM 8 in a step ST12. Thereafter the CPU1 erases the apparatus appearance patterns of FIGS. 4(a) and 4(b) in astep ST13, and transfers the apparatus appearance patterns of FIGS. 4(a)and 4(b) to the calculated next position and displays it on the same ina step ST14. Thus, one complete timer processing is finished. Theprocessing of shifting and displaying the apparatus appearance graphicdata will be described in detail later.

In this embodiment, the period of time for timer processing is set 2seconds. In other words, during the waiting condition, the appearancegraphic data displayed on the LCD 2 looks as if it moved around on theLCD 2 at regular intervals of 2 seconds.

It will be also preferable, instead of calculating the next displayposition in the steps ST12 to ST14, to memorize predetermined displaypositions to be shifted. Furthermore, it is needless to say thatpreparing three kinds of text plane screens for, e.g. characters,position fixed images, and position variable images in the VRAM 4 asshown in FIG. 3 will realize the similar display effect. Changing thedisplay like an animation in this manner will not only make the displaypleasant during the waiting (or stand-by) condition but let an operatoracknowledge at a glance that the apparatus is operating in a normalcondition.

Next, a case where the apparatus causes change will be explained below.If the CPU 1 detects in the steps ST9 and ST10 that the apparatuscondition is changed, the procedure goes on to a condition changeprocess routine shown in FIG. 7 in a step ST15.

Referring now to FIG. 7, this condition change process routine will beexplained in detail. First of all, the first mode previously definedwill be explained. FIG. 13 is a screen displayed on the LCD 2 when ahandset is hooked off or a monitor button is depressed for telephoneconversation.

If the hook off of the handset or the depression of the monitor buttonis detected in a step ST16, the CPU 1 exchanges the graphic data of FIG.4(a) for that of FIG. 4(b) and displays it on the LCD 2 in a step ST17.Subsequently, a dial number inputted through the numerical keys 27 by anoperator is displayed on the LCD 2 in a step ST18.

A screen displayed on the LCD 2 in this instance is composed in thefollowing manner. As previously explained referring to FIG. 3, thegraphic data displayed in the step ST17 is memorized in the image planescreen #1 in the VRAM 4. Meanwhile, the character data representingopponent phone number to be displayed in the step ST18 is memorized inthe text plane screen. And, the LCD controller 3 composes or combinesthese text plane and image plane screens into one screen to be displayedon the LCD 2.

If a response is returned from the opponent side after the step ST18,the LCD 2 displays a screen shown in FIG. 14.

In FIG. 14, a reference numeral 35 indicates a response icon and areference numeral 36 represents a communication icon. When a response isreturned from the opponent after the step ST18, the CPU 1 displays theresponse icon 35 in a step ST19 and further displays the communicationicon 36 together with communication time in a step ST20. In thisembodiment, the response icon 35 and the communication icon 36 arealready registered in the ROM 9 as character codes. Therefore the way ofdisplaying these icons 35, 36 is different from that of the dividedright and left graphic data. That is, the CPU 1 specifies the charactercode and then the first CG 5 outputs a corresponding bit pattern.Thereafter, thus obtained bit pattern is composed with the graphic dataindependently obtained by the LCD controller 3. This display ismemorized in the text plane screen #1 of the VRAM 4.

As the response icon 35 and the communication icon 36 can be bothhandled as character codes, the LCD controller 3 can simply and speedilyperform display operation by only designating the position of the LCD 2where these character codes 35, 36 are displayed. Furthermore, itbecomes possible to realize a unique display of operational mode changewhich looks as if the graphic data was altered, by only adding charactercodes without changing the graphic data.

If the conversation is finished, the CPU 1 responds it and commands theNCU 19 to disconnect the line in a step ST21, and further returns to theinitial screens shown by FIGS. 10 to 12 for standing by.

Next, the second mode will be explained. FIG. 15 shows a screen of theLCD 2 in the case where a manuscript is set on the apparatus for FAXtransmission or copy during the stand-by condition (step ST9).

At the time when the manuscript just set on the apparatus, the CPU 1cannot judge whether this manuscript is to be FAX transmitted or copied.Therefore, the CPU 1 displays all the functions necessary for FAXtransmission and copy as shown in FIG. 15.

Referring now to FIG. 7, an operation in the second mode will beexplained in detail.

It is checked in a step ST22 whether or not the manuscript is set forFAX transmission or copy. If the judgement is YES in the step ST22, theCPU 1 rewrites the graphic data memorized in the VRAM 4 from FIG. 4(c)to FIG. 4(d) and displays it on the LCD 2 in a step ST23. Then, afteradditionally displaying function frames in a step ST24, the CPU 1rewrites the character to be displayed in this function frame in a stepST25.

The screen displayed on the LCD 2 is composed in the following manner.That is, as previously explained with reference to FIG. 3, the imagedata of the function frame (to be displayed in the step ST24) ismemorized in the image plane screen #1 while the character datadisplayed in this function frame (to be displayed in the step ST25) ismemorized in the text plane screen #1. Then, the LCD controller 3composes these text plane and image plane screens into one screen to bedisplayed on the LCD 2. As the character data and the function frame arememorized in the different screens, the function frame can surround thecharacter data even if there is no sufficient space (e.g. one characterwidth) under the character data displayed. In other words, a display canbe made easy to see without losing display space.

In FIG. 15, an electronic phone book icon 37 represents an electronicphone book, which is already registered in the ROM 9 as a charactercode. This display is memorized in the text plane screen #1 in the VRAM4. Using such patterns in function display will enable users to easilyunderstand the content of display in the selection of functions ofapparatus. This electronic phone book icon 37 is equivalent to twocharacters; therefore it is twice as large as one character. It isneedless to say that the icon can be made large to be equivalent tothree characters or more. In the same manner, other graphic datadisplayed in the function frames are all registered in the ROM 9 ascharacter codes.

Accordingly, it becomes possible for the CPU 1 to handle each of thesegraphic data memorized in the ROM 9 as one of character data.Combination of these character codes will thus realize a quick displayof a large pattern, which used to be displayed by the image data.

In this case, to realize above-described pattern display consisting of aplurality of characters, dot patterns are determined in the followingmanner. At least one-line dot blank is provided between adjacent two,upper and lower, lines so as to prevent characters displayed in thesetwo lines from contacting with each other in an up-and-down direction.On the contrary, no dot blank is provided between two, right and left,rows because there is a necessity of connecting a plurality ofcharacters continuously in a right-and-left direction to form a singlelarge pattern.

Thereafter, the CPU 1 monitors in a step ST26 whether or not the copybutton, one of operation keys 28, is depressed.

FIG. 16 shows a screen displayed on the LCD 2 during the copy action.

If the copy button is depressed, the CPU 1 proceeds to a step ST27 andallows the apparatus to initiate a copy action under the conditiondetermined by the functions shown in FIG. 15. Furthermore, the CPU 1rewrites the graphic data memorized in the VRAM 4 from FIG. 4(d) to 4(e)and displays it on the LCD 2 in a step ST28. The apparatus appearancegraphic data displayed on the LCD 2 is composed by the LCD controller 3and memorized in the image plane screen #1 of the VRAM 4 as previouslyexplained referring to FIG. 3.

Thereafter in a step ST29, the CPU 1 not only displays an indication of"COPYING" near the apparatus appearance graphic data but activates acounter to count the number of copied pages and indicate the countednumber on the graphic data displayed on the LCD 2 so as to superimposeon the manuscript being presently fed. Such a display enables anoperator to immediately grasp the presently selected operation mode andits progress. The character data representing "PAGE" displayed on theLCD 2 is composed by the LCD controller 3 and memorized in the textplane screen #1 of the VRAM 4 as previously explained referring to FIG.3.

Subsequently in a step ST30, all the unnecessary function displayshaving no relation with copy action are erased from the LCD 2. This willbe welcome by a person who is not familiar with the operation of thisapparatus.

Thereafter, if the CPU 1 detects in a step ST31 that all the copy actionis finished, the CPU 1 returns to the initial screens shown by FIGS. 10to 12 for standing-by.

By the way, it is needless to say that, even after the mode has beenchanged by the function switches F1 through F4 explained below, the copyaction is performed in accordance with thus changed mode.

Next, the display of LCD 2 and processing action will be explained abouta case where other operations are performed after the manuscript is set.

First of all, the mode change by use of the function switches F1 throughF4 will be explained. The function switch F1 corresponds to light andshade, F2 to character size, F3 to half tone, F4 to finish stamp, and F5to electronic phone book, respectively.

As explained in the foregoing description, the screen of FIG. 15 isdisplayed when the manuscript is set. If the CPU 1 detects in a stepST32 that any one of function switches F1 through F4 is depressed, theCPU 1 responds this to adjust the specified or corresponding functionand rewrites the display content on the LCD 2 in a step ST33.

Next explained will be a case where the FAX transmission is executedafter the manuscript has been set. Described first of all with referenceto FIGS. 17 through 19 will be the way of display on the LCD 2 when theFAX transmission is performed by selecting an opponent phone number fromthe list memorized in the electronic phone book. FIG. 17 shows a screendisplayed on the LCD 2 when the electronic phone book is opened, FIG. 18shows a screen displayed on the LCD 2 when an opponent phone number isnow being called through the electronic phone book, and FIG. 19 shows ascreen displayed on the LCD 2 when the FAX transmission is progressingthrough the electronic phone book mode.

If the function switch F5 is depressed after the manuscript is set in astep ST34, the display on the LCD 2 is switched from the FIG. 15 to FIG.17 in a step ST35. As can be seen from FIGS. 15 and 17, layout ofgraphic data (electronic phone book icon 37) and character date ("PHONEBOOK") is different between FIGS. 15 and 17. Namely, the electronicphone book icon 37 and the character "PHONE BOOK" are arrayed in anup-and-down direction in the stand-by condition (FIG. 15) so that theycan be widely displayed in the function frame. Meanwhile, the electronicphone book icon 37 and the character "PHONE BOOK" are arrayed in anright-and-left direction in FIG. 17 so that sufficient display space canbe used for the content of the electronic phone book (phone numbers,opponent names, - - - ). As is previously described, the electronicphone book icon 37 is already registered in the ROM 9 as a charactercode. Therefore, the electronic phone book icon 37 is dealt with as oneof character code. This means that the LCD controller 3 can easily andquickly accomplish the layout change from vertical direction to lateraldirection by merely designating the display position of these charactercodes.

Next, in a step ST36, an opponent phone number is selected from the listmemorized in the electronic phone book (FIG. 17) by means of the scrollbutton 26 or numerical keys 27. Subsequently in a step ST37, the CPU 1automatically dials this number and displays an information explainingopponent name and phone number together with an indication of "CALLING"as shown in FIG. 18.

Thereafter, if the opponent side returns a response, the CPU 1 initiatesFAX transmission in a step ST38. Then an ID, sent from the opponentside, is displayed on the LCD 2 in a step ST39. Then, the graphic datais changed from FIG. 4(d) to FIG. 4(e) in a step ST40, and unnecessaryfunction displays of electronic phone book are erased in a step ST41.Subsequently, the counter is activated to count FAX transmitted pagesand displays the number of transmitted pages in a step ST42.

Although the number (i.e. 99 in FIG. 19) of the counter is continuouslyincremented in accordance with the progress of FAX transmission, thecharacter data "PAGE" (disposed at right side of 99 in FIG. 19) needsnot be changed. Therefore, the character data "PAGE" is alreadyregistered on the graphic data 4(e) in order to speed up the processingspeed of counter. If all the FAX transmission procedure is finished, theCPU 1 detects it in a step ST43 and returns to the initial screens ofFIGS. 10 to 12 for standing-by.

Next, the display operation of the LCD 2 will be explained about a casewhere an opponent phone number is directly inputted through thenumerical keys 27. In such a case, the FAX transmission is performed byhooking off the handset or depressing the monitor button after setting amanuscript.

FIG. 20 shows a screen on the LCD 2 when the handset is hooked off afterthe manuscript has been set. Furthermore, FIG. 21 shows a screen on theLCD 2 when the monitor button is depressed after the manuscript has beenset.

In FIG. 21, a dial tone icon 38 represents the detection of dial tone.If, in a step ST44, a user hooks off the handset for FAX transmissionafter setting a manuscript, the CPU 1 rewrites the graphic data fromFIG. 4(a) to FIG. 4(b) and displays it on the LCD 2 in a step ST45.

After the mode is set through previously described function switches F1through F4 and the handset is hooked off for FAX transmission, the CPU 1displays a character code "DIAL" which encourages a user to input aphone number, and flashes a cursor.

Thereafter, if an opponent phone number is inputted through thenumerical keys 27, the CPU 1 displays this inputted phone number on theLCD 2 in a step ST46. By the way, it is needless to say that the FAXtransmission can be performed after the user once talked with a personon the other end of the line.

Moreover, if in a step ST47 a user depresses the monitor button insteadof hooking off the handset, the CPU 1 additionally displays the dialtone icon 38 on the LCD 2 in a step ST48 together with the charactercode "DIAL" which encourages a user to input a phone number, and flashesa cursor. Thereafter, the same procedure as in the hook-off mode iscarried out. That is, when the opponent phone number is inputted throughthe numerical keys 27, the CPU 1 displays this inputted phone number onthe LCD 2 in the step ST46. If the opponent side returns a response, thedisplay on the LCD 2 is changed to FIG. 22 and FAX transmission isinitiated. Thereafter, the CPU 1 executes the steps ST38 through ST43 inthe same manner as in the electronic phone book mode. When all the FAXtransmission is finished, the CPU 1 detects it in the step ST43 andreturns to the initial screens of FIGS. 10 to 12.

If the FAX transmission mode is changed during its transmissionoperation, the LCD 2 displays a screen of FIG. 23. Then, if any one offunction switches F1 through F3 is depressed, this function changesetting becomes effective from the next manuscript to be transmitted.Meanwhile, if the function switch F4 is depressed, this function changesetting immediately becomes effective to a presently transmittingmanuscript. This is because the F4 function (i.e. finish stamp) isinitiated after one complete transmission of a manuscript is finished;while the F1˜F3 functions must transmit their information prior to amanuscript. Thus, from the display of FIG. 23, an operator can easilyknow about from which page the transmission mode is changed.

By the way, in the case where FAX transmission is performed by directlyinputting the opponent phone number through the numerical keys 27, theLCD 2 will display the screen of FIG. 22. Because an opponentinformation is not available, although it is available in the electronicphone book mode.

Next, the third mode will be explained. First explained will be a casewhere a telephone call is received during the stand-by condition ofFIGS. 10 to 12.

If a telephone call is received, the LCD 2 changes its display from theinitial screen to a screen of FIG. 24. In FIG. 24, a calling icon 39indicates that a call arrival signal is detected.

When received a call, the NCU 19 receives a call arrival signal of 16Hzin a step ST49. As a called discrimination signal, which is received incase of FAX mode, is not received in this telephone call in a step ST50,the CPU 1 additionally displays the calling icon 39 on the LCD 2 in astep ST51. In this embodiment the calling icon 39 is already registeredin the ROM 9 as a character code; therefore this display is memorized inthe text plane screen #1 of the VRAM 4.

FIG. 25 shows a screen displayed on the LCD 2 when an user hooks off thehandset in response to this call.

When the user hooks off the handset, the CPU 1 rewrites the graphic datafrom FIG. 4(a) to FIG. 4(b) and additionally displays the response icon35 in a step ST52. In this embodiment the response icon 35 is alreadyregistered in the CPU 9 as a character code, and this display ismemorized in the text plane screen #1 of the VRAM 4. On the other hand,the graphic data rewritten in the step ST52 is memorized in the imageplane screen of the VRAM 4.

Thereafter, if the communication is finished, the CPU 1 notifies the NCU19 of an interruption of the line in a step ST53, and returns to theinitial screens of FIGS. 10 to 12.

Next explained will be a case where FAX transmission is received duringthe stand-by condition. FIG. 26 shows a screen displayed on the LCD 2when the FAX transmission is received.

When received the FAX transmission, the NCU 19 receives the call arrivalsignal of 16 Hz in the step ST49 in the same manner as in the telephonecall. If the apparatus is set to FAX receiving mode or automaticreceiving mode, this 16 Hz arrival signal will automatically hook offthe phone and detects the called discrimination signal. If the calleddiscrimination signal is received, the CPU 1 judges it as FAXtransmission. If not, the CPU 1 recognizes it as telephone call.

After detecting the called discrimination signal in the step ST50, theCPU 1 initiates the FAX reception in a step ST54. Then, the CPU 1rewrites the graphic data from FIGS. 4(c) to FIG. 4(f) and displays iton the LCD 2 in a step ST55. Also, the counter is activated to countpages received and an indication of "FAX RECEIVING" is displayed atright side of the graphic data representing appearance of the apparatus.And, the number of received pages (e.g. 99 in an example of FIG. 26) isdisplayed on a recording paper portion of the graphic data. Furthermore,the CPU 1 receives the ID information being sent from the opponent sidecomposes it on this display screen in a step ST56.

In this case, the page number, the character code "FAX RECEIVING", andthe ID information are composed and memorized onto the text plane screenof the VRAM 4 by the LCD controller 3 as previously explained in detailwith reference to FIG. 3. Meanwhile, the graphic data representing anappearance of apparatus is composed and memorized onto the image planescreen of the VRAM 4 by the LCD controller 3.

Thereafter, if the CPU 1 detects in a step ST57 that the reception isfinished, the CPU 1 notifies the NCU 19 that the line is interrupted ina step ST58 and then returns to the initial screens of FIGS. 10 to 12for standing by.

Next, the fourth mode will be explained. First explained will be a casewhere an external phone is used during the stand-by condition. FIG. 27shows a screen displayed on the LCD 2 when the external phone is used.

In FIG. 27, an external phone using icon 40 indicates that the externalphone is now used. If the usage of the external phone is detected in astep ST59, the CPU 1 detects it and additionally displays the externalphone using icon 40 together with a character code "EXTERNAL PHONEUSING" in a step ST60. In this embodiment, the external phone using icon40 is already registered in the ROM 9 as a character code and ismemorized in the text plane screen of the VRAM 4.

Though these character code "EXTERNAL PHONE USING" and the externalphone using icon 40 are both character codes, combining them willrealize a unique display as if the graphic image was used. Furthermore,if there is no sufficient display space, usage of the external phoneusing icon 40 only will be acceptable to notify users of the presentoperating mode. Furthermore, the character code "EXTERNAL PHONE USING"is memorized in the text plane screen #1 as explained in detail withreference to FIG. 3.

FIG. 28 shows a screen displayed on the LCD 2 when the external phone iscalled. In FIG. 28, an external phone calling icon 41 indicates that theexternal phone is called. When the external phone is called, the CPU 1displays the external phone calling icon 41 together with a charactercode "EXTERNAL PHONE CALLING" as shown in FIG. 28.

As previously described, the external phone calling icon 41 and theexternal phone using icon 40 can be both handled as character codes. Ifthese icons 40, 41 are alternately displayed, the display of the LCD 2will look like an animation.

By the way, if the F1 switch, corresponding to the menu mode, isdepressed during the stand-by condition, the LCD 2 displays a main menucontaining a number of actions, e.g. electronic phone book register,user register including modification/registration of ID information,list print, execution of poling reception, transfer to card program etc.

If the F5 switch, corresponding to the electronic phone mode, isdepressed, the list in the electronic phone book is displayed.

4. Graphic data transfer/display Processing Hereinafter,transfer/display processing of graphic data to the LCD 2 and processingof memory card will be explained in detail. FIG. 9 is a subroutineshowing the transfer/display processing of graphic data, whichcorresponds to steps ST5, ST6, ST14, ST17, ST23, ST28, ST40, ST45, ST52and ST55.

Referring now to FIG. 9, the transfer/display processing of the graphicdata representing the appearance of the apparatus will be explained indetail in accordance with the present invention. Let's suppose that FIG.4(a) is displayed as a graphic data.

If the CPU 1 specifies FIG. 4(a), the LCD controller 3 obtains anaddress storing FIG. 4(a) from ROM 9 in a step ST100. The ROM 9basically consists of a data-address memory portion and a compresseddata memory portion. The data-address memory portion memorizes Thegraphic data FIGS. 4(a) through 4(f), respectively representing anappearance of the apparatus, are compressed and stored in predeterminedaddresses in the ROM 9. The data-address memory portion memorizes therelationship between each compressed graphic data and its address in theROM 9, while the compressed data memory portion memorizes the compressedgraphic data themselves.

Next in a step ST101, the CPU 1 reconstructs the dot image of 8 bytes tobe displayed on the LCD 2 on the basis of the data corresponding to thecompressed graphic data of FIG. 4(a), which corresponding to the addressobtained in the step ST100.

Then in a step ST102, the CPU 1 sets the LCD controller 3 a head addressin the VRAM 4 to which the reconstructed dot image is transferred. Inmore detail, the head address indicates the position of the head data ofFIG. 4(a) on the LCD 2.

As the graphic data is transmitted by a data length of 8 bytes, it isnecessary in this embodiment to specify a position of the next 8-bytedata. To determine the address to which the 8-byte data is transferred,the following equation is used in a step ST103.

Actual Address=Address of ST102+40 * Loop Number

Wherein, the loop number (an integer) is 0 in the first loop and isincremented by 1 as the loop is renewed.

Thereafter, the specified 8-byte graphic data is transferred to the VRAM4, i.e. to thus calculated address, in a step ST104. Then, the datatransfer processing of steps ST101 through ST104 is continuouslyrepeated until all the data representing FIG. 4(a) is completelytransferred into the VRAM 4. If the CPU 1 detects in a step ST105 thatall the transfer processing is finished, the CPU 1 returns to each stepof FIGS. 6 to 8.

Although a method of circulating the graphic data to realize ananimation-like display is previously described, it can be realized bytransferring while data. That is, the presently displayed graphic datacan be erased by superimposing with the white data.

5. Memory Card Processing

FIG. 29 is a schematic block diagram showing insertion/extractioncontrol of the memory card in the information processing system inaccordance with the present invention.

In FIG. 29, a reference numeral 42 represents a reset IC which resetsthe CPU 1 when the memory card is pulled out of a connector 11. Aswitching transistor 43 supplies electric power to the memory card 12. Abuffer 44 connects the memory card 12 and the CPU 1 by bus. A referencenumeral 45 represents a parallel peripheral interface (hereinafterabbreviated by PPI). This PPI 45 inputs an address bus signal and a databus signal from the bus between the CPU 1 and the memory card 12. ThePPI 45 further inputs a card insertion signal in order to check thepresence of the memory card 12. This card insertion signal is producedby an OR circuit which inputs check digit (abbreviated by CD)1 and CD2provided both ends of the card pins.

The PPI 45 outputs a power enable signal which allows the switchingtransistor 43 to supply electric power to the memory card 12, and alsooutputs a bus enable signal to a gate of the buffer 44 so as to allowbus connection between the CPU 1 and the memory card 12. A flip-flop 46inputs an AND result of three, i.e. power enable, bus enable, and resetenable, signals. And, the flip-flop 46 outputs the card insertion signalto a NOR circuit, whose the other input is connected to the reset IC 42.

In FIG. 29, the same components as those of FIG. 1 are suffixed by thesame numerals and will be no more explained. Referring now to FIG. 29,the insertion/extraction control of the memory card will be explained indetail.

By inserting the memory card 12 into the connector 11 provided in theapparatus main body, the CD1 and CD2 disposed at both ends of connectingpins are grounded in the memory card 12. These CD1 and CD2 thereforebecomes a LOW-level; therefore the card insertion signal, which is ORresult of these CD1 and CD2 signals, becomes a LOW-level.

In response to this LOW-level signal, the PPI 45 feeds a HIGH-levelpower enable signal to the switching transistor 43 and a HIGH-level busenable signal to the buffer 44. Furthermore, the PPI 45 feeds aHIGH-level reset enable signal to one input terminal of the AND circuit,whose the other input terminal is connected to another AND circuitinputting both the power enable signal and the bus enable signal. Anoutput of this AND circuit is the reset enable signal of the memory card12. This reset enable signal is inputted into an clear terminal of theflip-flop 46. As long as the memory card 12 runs its program, thisflip-flop 46 feeds a LOW-level signal to one input terminal of the NORcircuit whose the other input terminal is connected to the reset IC 42.If either of the flip-flop 46 or the reset IC 42 inputs a HIGH-levelsignal into the NOR circuit, a reset signal of LOW-level will be fedfrom this NOR circuit to the CPU 1.

Next, a reset action of the CPU 1 will be explained. First of all, if anelectric power voltage supplied to the system is lowered due to turningoff of electric power or other reasons, the reset IC 42 will generates areset signal at the time when the voltage reduces to a predeterminedlevel within a range wherein the CPU 1 causes no malfunction. With thisarrangement, the CPU 1 can terminate its action without causingmalfunction due to excessive voltage drop. As this reset signal isinputted into the NOR circuit which is connected most closest to thereset terminal of the CPU 1, the reset control of the CPU 1 can beperformed regardless of the presence of the memory card 12.

Next, the reset control by the extraction of the memory card 12 will beexplained. If the memory card 12 is extracted from the connector 11, theCD1 and CD2 will be nongrounded or HIGH-level. This HIGH-level cardinsertion signal is inputted into the NOR circuit through the flip-flop46. The NOR circuit outputs a LOW-level signal to the reset terminal ofthe CPU 1, thereby resetting the CPU 1 without causing malfunction dueto extraction of memory card.

Even if the memory card 12 is surely inserted in the connector 11, theflip-flop 46 receives no reset enable signal at its clear terminal whenthe memory card runs no program. Therefore, the CPU 1 is not reset whenthe memory card is extracted. Because no HIGH-level signal istransmitted to the NOR circuit by the interruption of the flip-flop 46.

6. System Operation with Memory Card

FIG. 30 is a flowchart showing an action of the information processingsystem of the present invention with a memory card functionallyincorporated therein. This action flow is processed when the presence ofmemory card is detected through the judgement of the step ST3 in FIG. 6.

In FIG. 30, if the memory card is inserted when the system is in thestand-by condition in a step ST300 (memory card IF check confirmationflag is set), it is checked in a step ST301 whether or not the CD1 andCD2 turn to LOW-level. If no memory card is inserted in the step ST300,the CPU 1 resumes the main program and the LCD 2 displays the initialscreen of FIG. 10 which shows no memory card is contained. If the memorycard is inserted in the step ST300, the power enable signal is outputtedto the switching transistor so as to supply electric power to the memorycard in a step ST302 and the bus enable signal is outputted to thebuffer 44 so as to connect the CPU 1 and the memory card 12 in a stepST303. Then, an attribute information is read out from a specificaddress in the ROM 122 of the memory card 12 in a step ST304.Hereinafter, this attribute information will be explained.

FIG. 31 shows a memory map of the memory card used in this embodiment.In FIG. 31, first attribute information 47 is a device information whichstores device kind, capacity, and access speed of the memory card.Second attribute information 48 is a level-1 version product informationwhich stores JEIDA (Japan Electronic Industry Development Association)specification version, product maker information, and product versioninformation. Third attribute information 49 is a level-2 version productinformation which stored specification version, specification referencelevel, initial data address information, maker individual information,initialize maker name, and card information. An entry table 50 memorizeswhere each module or entry point table including icon information isstored in this memory card. A program area 51 stores programs andgraphic data of various icons.

After reading out the attribute information, the CPU 1 checks in a stepST305 whether or not the attribute of the memory card is valid to thesystem. If invalid, an alarm is indicated in a step ST306 and theelectric power supply to the memory card is stopped in a step ST307.Furthermore, the memory card is disconnected from the system bus in astep ST308. Thereafter, it is checked in a step ST309 if the memory cardis extracted or not? If the memory card is extracted, the alarmindication is stopped and the CPU 1 returns to the stand-by condition.

The CPU 1 detects in the step ST305 that the attribute of the memorycard is valid. Then in a step ST310, the CPU 1 transfers menu icon data,memorized in the form of dot image, from the EEPROM 123 of the memorycard 12 to the VRAM 4 and displays it. In this case the CPU 1 obtains anaddress, storing the dot image of the menu icon data, from the entrytable 50. If this memory card contains a menu icon data produced andmemorized optionally by a user, the CPU 1 obtains from the entry table50 an address storing the dot image representing this user defining menuicon data. As the menu icon data are basically memorized in the form ofdot image, this embodiment allows users to optionally create icon data.FIGS. 11 and 12 are the screens displayed on the LCD 2 in this case. Asapparent from these drawings, there is no difference between menu iconsdisplayed on the LCD 2. In other words, these icons displayed on the LCD2 are so similar that it is impossible to identify whether each iconbelongs to the memory card or the system.

After displaying the menu icon data on the LCD 2, the CPU 1 judgeswhether or not a unique code of the RAM 8 coincides with a unique codeof the EEPROM 123 in a step ST311. More specifically, the unique code(i.e. ID) is time data such as month, day, hour, minute, and second. Andthis time data is generated by a clock in the information processingapparatus when the memory card is inserted into the informationprocessing apparatus. As the judgement of valid/invalid about the datamemorized in the RAM 8 can be performed through this judgement in thestep ST311, there is no necessity of initializing the RAM 8 every timewhen the memory card is inserted or extracted. Furthermore, if aninserted memory card is identical to the previously extracted memorycard, the information already memorized in the ROM 8 can be utilizedwithout any change. No down load of necessary data will be requiredalso.

When the unique codes are not identical with each other in the stepST312, a system data invalid flag is set in the RAM 8 in a step ST313and renews time data to coincide with that of the memory card in a stepST314.

When the unique codes are identical with each other in the step ST312, asystem data valid flag is set in the RAM 8 in a step ST315 and norenewal of time data of the RAM 8 is carried out.

Thereafter, the CPU 1 judges in a step ST316 whether or not the programof the memory card is selected. If the card program is selected, asystem reset valid flag is set in a step ST317 and proceeds to the cardprogram in a step ST318. Subsequently, the CPU monitors the extractionof the memory card in a step ST320 until the card program ends in a stepST 319.

If the memory card is extracted when the card program is still running,an arrangement of FIG. 29 will reset the system in a step ST321 toprotect self run away phenomenon. Accordingly, it becomes possible toinsert or extract without turning off the electric power of the system.Even if the electric power is broken down due to some extraordinariness,the CPU 1 will cause no malfunction and also the data of the memory cardwill be adequately protected.

Furthermore, the system in accordance with this embodiment allows, evenif the system is reset in the step ST321, to use the data memorized inthe RAM 8 by checking the previously described unique codes unless adifferent memory card is inserted. This enables the system toimmediately resume the previous condition after reset.

If the data memorized in the ROM 8 is maintained valid for a while untilthe different card is surely selected after the coincidence check of theunique codes, it will become possible to prevent the data in the RAM 8from being undesirably aborted when another memory card is mistakenlyinserted.

7. Inquiry and Communication Operation

Next, an inquiry and communication action of this embodiment of thepresent invention will be described with reference to FIGS. 32(a), 32(b)and 33 through 54.

Recent development in the information processing system has realized thebanking systems, captain systems, personal computer communications andthe like. FIG. 54 shows a generic construction of an inquiry andcommunication system. In FIG. 54, an information center 100 receivesinformation offered from data sources and occasionally registers andrenews them to construct a data base 200. These data base 200 arenormally accessible from an information processing terminal 400 througha communication network 300. Upon retrieval request from the informationprocessing terminal 400, the information center 100 provides a requestedinformation from the data base 200 to the terminal 400. The informationprovided from the data base 200 is normally displayed on a displayapparatus provided in the terminal 400 or fed to a recording apparatus.

First of all, FIG. 32(a) is a flowchart showing an inquiry andcommunication action of this embodiment, while FIG. 32(b) is a timesequence showing this inquiry and communication action.

FIG. 33 is an initial screen including an information inquiry function.This initial screen is displayed when the memory card 12, memorizing acommunication application program compatible with various informationprocessing centers, is inserted into the connector 11 of the system mainbody. An information inquiry icon 52 is displayed within a correspondingfunction frame on the LCD 2, that informs an operator of the informationinquiry service being available.

If the function frame F2 is depressed, the display on the LCD 2 ischanged to a screen of FIG. 34 which instructs an operator to enter apassword. Next, if the execution/correction key 30 on the operationpanel is depressed after inputting a predetermined password, it isjudged whether or not the input password is correct. If judged correct,a main menu of the information service is displayed on the LCD 2 asshown in FIG. 35.

Upon selection of, for example, "1: RECEIVE INFORMATION RETRIEVALSERVICE" through the numerical keys 27 on the operation panel, thedisplay on the LCD 2 is changed to a screen of FIG. 36. In order tospecify an information center, a center code and a subscriber number aresuccessively inputted. Then, if one of numerous information centers isspecified, the system comes into a condition for waiting for an ID(identification) number. A space 53 for "MEMO" may be used by a user forinputting optional information such as an information center name.

Next, once the ID number is inputted as shown in FIG. 37, a newindication "CONNECT" is displayed just above the function switch F1. Ifthe operator depressed this function switch F1, the action flow of FIG.32(a) will be executed.

In FIG. 32(a), a message "NOW ACCESSING: WAIT A MOMENT, PLEASE" isdisplayed in a step ST501. In this instance, a procedure necessary forconnecting the system with the information center is executed. That is,the system automatically dials the telephone number of the informationcenter having been registered beforehand. If the line is connected, amodem connection is next performed in compliance with the connectregulation for personal computer communication modems (an advice V25 byCCITT). Then, the message "NOW ACCESSING: WAIT A MOMENT, PLEASE" flasheson the LCD 2.

If the connection between the system and the information center iscompleted, the information center requests an ID number of the system orcapacity information. In response to this request, the systemautomatically returns the ID number registered. In a step ST502, aservice menu is displayed on the LCD 2. Namely, after confirming the IDnumber of the system, the information center transmits the service menureserved therein to the system.

The operator selects one of items in the service menu by inputtingcorresponding service number through the numerical keys 27. Thusselected number is transmitted to the information center. As the servicemenu has a structure in the form of tree, a sub service menu isdisplayed as shown in FIG. 40 in a step ST503. With this hierarchicaltree structure the content of the menu can be classified into amulti-level form; hence the user can perform a desired informationretrieval by simply manipulating the numerical keys 27. The functionswitch F4, above which an indication "NEXT PAGE" is displayed, may bedepressed in the case where a service menu or sub service menu bridges aplurality of pages.

In a step ST504, the inquiry information selected in the steps ST502 andST503 is stored. (The LCD 2 does not display this inquiry informationspecially.) The selected inquiry information is transmitted to theinformation center, which thereafter retrieves the data base 200 tocollect the requested information and reads out them as the resultantinquiry information. The resultant inquiry information are successivelytransmitted from the information center to the system, which thenreturns a confirmation code every time when a complete one page has beenreceived. The system, however, sends out no confirmation code when thelast page has been received. Instead, a confirmation/continuationrequest code will be transmitted to the information center as will bedescribed later in a step ST512. In other words, thisconfirmation/continuation request code represents the last page of theresultant inquiry information having been read out, and also indicatesthe next process (i.e. continuation of retrieval or interruption ofretrieval).

The resultant inquiry information are successively stored in the RAM 8.FIG. 48 shows a detailed structure of the RAM 8. The RAM 8 essentiallyconsists of an administration table area and a reserved screen area. Theadministration table area comprises a reserved screen information number54, a print reservation number 55, a reserved/retrieved informationnumber 56, a retrieval time/hour 57, a flag 58 representing e.g. totalpages of the resultant inquiry information, and a character buffernumber 59 representing a character buffer number storing the resultantinquiry information. On the other hand, the reserved screen area storesthe resultant inquiry information classified in accordance with thecharacter buffer number 59. Although the RAM 8 is divided into two,administration table and reserved screen, areas, it is needless to saythat two RAMs can be provided exclusively for these areas.

The number of pages allowed for the print reservation is restricted bythe number of the character buffers 1, 2 - - - in the reserved screenarea. When the reserved screen area is filled up, the system disconnectsthe line and prints out the reserved screens. If the reserved screenarea is filled at an intermediate portion of a page, this page will notbe printed out.

Then, if the line is disconnected before the retrieval is finished, thedisplay on the LCD 2 resumes a main menu shown in FIG. 47 afterfinishing the printout operation. This main manu of FIG. 47 is displayedonly when the line is disconnected during the retrieval, and isdifferent from the previous main menu in that an item "6. CONNECT LINEAGAIN" is additionally displayed. This item allows, if selected, anautomatic return to the interrupted retrieval without repetition of thesame manual procedure.

In a step ST505, a first page of inquiry information is displayed on theLCD 2 after all the resultant information is stored in the RAM 8, Then,it is checked in a step ST506 whether or not the inquiry informationpage displayed present is last. If not, an indication "NEXT PAGE" isdisplayed above the function switch F4. An operator may depress thisfunction switch F4 to see the next page. In this manner, the operatorcan confirm every page by successively displaying it on the LCD 2.

When the inquiry information page is last, the CPU 1 proceeds to a stepST507 wherein the display questions whether or not the next retrievalshould be done. In this case an indication "CONTENTS" is displayed abovethe function switch F2, also an indication "CONTINUE" the functionswitch F3 and an indication "END" the function switch F5, respectively.(Refer to FIGS. 41, 42, 43, and 44) If the "CONTENTS" is selected, thedisplay screen returns to the menu screen. In the same manner, if the"CONTINUE" is selected, the display screen returns to the sub servicemenu screen, and if "END" to the procedure for disconnecting the line.

Next, it is judged in a step ST508 whether or not an automatic print isreserved. If automatic print is selected, all the inquiry information issuccessively stored in the RAM 8. And, the number of the inquiryinformation is added as a print number in a step ST510.

If the automatic print is not selected, a question "DO YOU WANTRESULTANT INFORMATION PRINTED ?" is displayed on the LCD 2 as shown inFIG. 45 in a step ST509. Then, if the function switch F1, above which anindication "YES" is displayed, is depressed the print reservation of thedisplayed inquiry information is completed. The print reservation in thestep ST510 is carried out in the following manner.

In the RAM 8, the reserved screen information number area 54 memorizesan inquiry information number stored in the RAM 8, i.e. a summation ofpreviously reserved inquiry information number and a presently receivedscreen number. Next, the inquiry information number, having beenreserved a printing, is counted occasionally. The count result is storedin the RAM 8 as a print reservation number 55. This print reservationnumber is, for example, displayed on the display screen as shown in FIG.41.

On the other hand, if the print reservation is not selected in the stepST508, the following procedure will be performed. Namely, the inquiryinformation stored in the step ST504 is erased. More particularly, thisinquiry information or its related data are erased from the memory areasof the reserved/retrieved information name 56, the retrieved time/hour57, the flag 58, the character buffer number 59, and its correspondingcharacter buffer 60. In this case, the print reservation number 55 isnot incremented and holds the previous number. Also, the reserved screeninformation number 54 is subtracted by an amount of the presentlyreceived inquiry information pages so as to coincide with the printreservation number 55.

Furthermore, if "CONTENTS" or "CONTINUE" was selected in the step ST507,the CPU 1 proceeds to the step ST502 in case of "CONTENTS" or ST503 incase of "CONTINUE" in s step ST512. If "END" is selected in the stepST507, the CPU 1 proceeds to the step ST513 wherein the line isdisconnected. In more detail, an end screen shown in FIG. 46 isdisplayed in this step ST513, which informs an user of a communicationcharge. Thereafter the information center sends out a line disconnectionsignal; while the system returns a line disconnection acknowledge signalto the information center. Then the line is finally disconnected.

Next, the system checks whether or not the print reservation numberreserved in the step ST509 is 0. If the print reservation number is 0,the display screen returns to the initial screen. If not, the CPU 1performs a predetermined condition check including, e.g. paper remainingamount, door open. If the normal condition of apparatus is confirmedthrough this condition check, the print operation of the acquiredinquiry information is carried out in a step ST514. In this step ST514 ascreen of FIG. 46 is displayed, which includes an message "NOW PRINTING:WAIT A MOMENT, PLEASE." flashing at the bottom. And all the designatedinquiry information is printed out.

If the electric power of the system is accidentally broken down duringthe inquiry information retrieval, it is necessary to turn on theelectric power and enter the password again to print out the inquiryinformation stored in the RAM 8. The RAM 8 has a memory structurecapably of preventing the stored information from being aborted even ifthe electric power is broken down.

8. Printout Operation

The printout action of this embodiment will be explained below withreference to FIGS. 49 through 53, which respectively shows a printformat (or pattern).

Header information of the reserved/retrieved information name storingarea 56, the retrieved time/hour storing area 57, and the flag storingarea 58 are transmitted the printer 22. The printer 22 is equipped witha buffer memory (not shown) capable of storing full data of 1 line. Theheader information are stored as code information, which will be latertransformed by the CG2 into font data to be printed out.

After the printing out operation of the header information, the inquiryinformation is printed out. In this case, it is judged from the flagstoring area 58 whether or not the pages of the inquiry information isplural. In case of plural pages, these inquiry information are printedas a series of information in a format shown in FIG. 49.

Then, if another reserved/retrieved information name is stored in theadministration table area, it is judged that another inquiry informationretrieved in accordance to another service menu is stored. Therefore,this another inquiry information is printed together with new headerinformation. As each inquiry information is paired with the headerinformation, no confusion will occur in the printing operation. Forexample, different kinds information will not be printed out together ina mixed condition.

The RAM 8 stores these header information. By checking flags identifyingindividual header information, it will be found that these pluralinquiry information are a series of information. The flag represents,for example, the page number 1, 2, - - - of the inquiry information.Based on this page number, the order of the inquiry information can beknown.

By the way, the character buffer stores these inquiry information in theform of code information. A line end mark representing an end of a lineis also stored.

Assuming that three screens are arrayed in the same record sheet alongthe main scanning direction, a first line data of each screen issuccessively transmitted to the buffer memory in the order of No. 1screen, No. 2 screen, and No. 3 screen.

The buffer memory has a capacity sufficient to hold the inquiryinformation amount equivalent to the printed characters number (15characters in this embodiment)×3 per line. The inquiry information ofNo. 2 screen is stored from 16th character from the left, and the No. 3is from 31st.

After transmitting all the first lines of three, from No. 1 to No. 3,screens, the CG2 transforms these code information into font data. Then,these font data will be printed out. As the three screens are printedtogether by being arrayed along the main scanning direction as apparentfrom the explanation above, a record sheet can be effectively usedwithout wasting its righthand space.

Furthermore, in FIG. 49, the retrieval information such as the centercode and service name, inputted in advance for retrieval in the database of the information center, are printed together as headerinformation.

In the case where the information processing system of this embodimentis a facsimile type, the LCD 2 will be able to display 20 full-sizecharacters along the main scanning direction. Among them, 14 charactersfrom the left end will be used for the display of inquiry information.It will be necessary to take 24 dots for a print character font and 8dots for a clearance between characters, and hence 32 dots in total forone character. A lateral dot number of the 14 characters on the LCD 2 is32×14=448. On the other hand, an A4 sized record paper has a width of1680 dots/210 mm. Therefore, not only the simultaneous printing of threescreens being laterally arrayed becomes possible but there is still somemargins remaining (1680=448×3+336).

FIGS. 50 through 53 respectively shows a print format. Although theprint format of FIG. 49 surrounds each block of information by a dottedline frame, using such an image information of dotted line frame cansurely make the display easy to see.

The print format shown in FIG. 50 is similar to that of FIG. 49 butdifferent in using a solid line frame. The print format shown in FIG. 51is different in using an image information representing a corner.Providing only one corner per information block would bring the sameeffect as the print format of FIG. 50. It will be advantageous inreducing an overall printing time.

The print format shown in FIG. 52 is similar to that of FIG. 51 butdifferent in using a laterally elongated corner line. The print formatshown in FIG. 53 is similar to that of FIG. 52 but different insubstituting a dotted line for a solid line. These image informationcomposed with the inquiry information are memorized in an appropriatememory means such as the RAM 8 in advance, and it is needless to saythat various modification will be further possible.
